Testimony in the preliminary hearing for two men accused in the attack on a San Francisco Giants fan outside Dodger Stadium after the 2011 opening day game resumed Friday afternoon.

Louie Sanchez and Mavin Norwood are charged with one felony count each of mayhem, assault by means likely to produce great bodily injury and battery with serious bodily injury, along with the allegation that the two inflicted great bodily injury on Bay Area paramedic Bryan Stow. Sanchez is also charged with a misdemeanor count of battery involving a run-in with a female Giants fan and a misdemeanor battery count for allegedly swinging his fist at a young man in a group of Giants fans in the parking lot after the game.

Witness Testifies to Suspects' Behavior Prior to Stow Beating

A witness who attended the Dodgers game after which Bryan Stow was brutally beaten in the parking lot described two Dodgers fans who pushed and punched a teenager and shouted obscenties at other fans. When asked how the Giants fans reacted to their taunts, she testified, "'We don't want no trouble.'" Patrick Healy reports for the NBC4 News at 5 p.m. on May 31, 2012.

One of Stow's sisters might testify during Friday's session, which is scheduled to begin at about 1:30 p.m. The preliminary hearing will be used to determine whether the is enough evidence for Norwood and Sanchez to stand trial.

The preliminary phase began earlier this week with testimony from other fans who attended the game and investigators. Two women testified Thursday that they heard Stow fall to the ground after he was punched in the head during a parking lot confrontation.

"I heard Bryan (Stow) hit the pavement. It sounded like a thud, like someone's head was smashing (against) the pavement,'' Megan Duffy testified. "And then I saw Bryan get kicked in the head by the same gentleman I saw throw the punch."

"Did he appear to be conscious?'' Deputy District Attorney Michele Hanisee asked.

"No,'' the prosecution witness responded, noting that she called 911 to get help for Stow.

Duffy testified that she only got a side view of the man who punched and kicked Stow, but that she got a better view of another man who landed on the hood of her black sport-utility vehicle during the altercation in Lot 2. She said she was later shown photographs by police and chose a photo -- of Norwood - - as the man she believed had landed on the top of her vehicle's hood.

She noted that Stow "had Giants attire on'' and "was lying unconscious on the ground'' after the attack.

Joann Cerda, who was also walking in the parking lot after the game, testified that she saw two Dodgers fans and four Giants fans and witnessed a "verbal altercation'' in which the Giants fans were trying to stop the dispute and attempting to walk away.

"I saw Bryan Stow standing by himself ... One of the suspects hit him on the side of his face,'' she said. "Bryan Stow immediately fell backwards and his head .. hit the concrete. It was rather loud.''

Stow suffered a fracture to his skull that resulted in the loss of a portion of his skull as well as damage to his brain according to a stipulation signed by attorneys from both sides and read in court.

Stow is currently "unable to walk, has loss of motor skills in his arms and hands, is unable to carry on a normal conversation, unable to control his bodily functions, and unable to care for himself due to diffuse, severe, traumatic brain injury,'' according to the signed stipulation.
